WILLIAM F. BAYER, OF BUFFALO, NEW YORK, ASSIGNOR TO CHASE & BAKER COM- PANY, OF BUFFALO, NEW YORK, A CORPORATION OF NEW YORK.

SPOOL FOR MUSIC-SHEETS.

Specification of Letters Patent.

Application filed August 21, 1908.

To all whom it may concern:

Be it known that I, WILLIAM F. BAYER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Spools for Musicfiheets, of which the following is a specification.

This invention relates to the flanged rolls or spools upon which perforated music sheets are wound, and more particularly to rolls of this kind in which one or both end-flanges are yieldable or adjustable lengthwise of the spool to compensate for variations in the width of the music sheet due to atmospheric changes or other causes.

The object of my invention is the provision of an improved roll of this character in which the compensating device is'neat and simple in construction and so organized as to permit rewinding of the music sheet without binding or restraint of any kind.

In the accompanying drawings: Figure 1 is a side elevation of a music roll embodying the invention. Fig. 2 is an enlarged longitudinal section thereof. Fig. 3 is an end view of the same. Fig. 4 is a transverse section in line 4E4;, Fig. 2. Fig. 5 is a fragmentary longitudinal section of the roll, showing a modified construction thereof.

Similar letters of reference indicate corresponding parts throughout the several views.

A indicates the body of the roll or spool which latter may be either a music-roll or a take-up roll. It preferably consists of a pressed-paper tube, but may be constructed of wood or other suitable material. In the ends of this tubular body are secured plugs B, preferably of wood, having reduced outer portions 1) forming axial studs which project beyond the ends of the body. Driven into or otherwise secured to the ends of these studs are metallic journals 0 which are supported in the customary bearings not shown in the drawings. If desired, the roll may be provided with other suitable or well-known means for j ournaling it in such bearings.

D, D indicate the end flanges of the roll, one of which, say D, is rigidly secured upon the adjacent stud Z) by driving or otherwise. The other flange D is slidable lengthwise of the roll and mounted on a sleeve or thimble E surrounding the adjacent stud Z) upon which it is tightly driven or otherwise secured. The outer portion of the bore of the flange D is enlarged or recessed, as shown at d, while its contracted inner portion may contain a metallic bushing al provided at its outer end with a flange d which bears against the bottom of said recess. This bushing is, however, non-essential and may be omitted, if desired.

Mounted on the thimble E and extending into the recess cl is a cap preferably consisting of a collar 7 having at its outer end an inwardly-turned flange j which abuts against a projecting flange g at the outer end of the thimble. Between said collar and the flange of the bushing d a spring h is interposed which surrounds the thimble E and is incased by said cap and the recessed roll-flange D The collar f is of sufficient width to extend into the recess (Z in all positions of the movable roll-flange D The spring 7t finds its abutment against the collar f which in turn abuts against the flange of the fixed thimble E and the pressure of the spring is exerted inwardly against the flanged bushing 61 which practically forms an internal shoulder of the roll-flange D The latter is thus constantly pressed toward the opposite flange D, closely confining the music sheet between the flanges and causing it to track properly, while at the same time permitting the movable flange to accommodate itself to variations in the width of the sheet.

When the music-roll is placed in its customary bearings, the pressure of the latter is not exerted against the flanges D, D but against the end of the stud b at the right hand end of the roll and the end of the journal 0 at its other end, and the roll is therefore free to rotate without binding both in taking up and rewinding the music sheet.

If desired, the flanged thimble and the cap may be formed in one piece, as shown in Fig. 5, E indicating the thimble and f the cap.

I claim as my invention:

1. A music roll provided at its end with a stud, a cap mounted on said stud and held against outward displacement thereon, a roll-flange mounted on said stud on the inner side of said cap and provided in its outer side with a recess which receives the cap, and a spring arranged in said recess and said cap and bearing at its ends against the cap and the bottom of the recess.

2. A music roll provided at its end with a stud, a sleeve mounted on said stud and.

having an abutment, a flange slidably mounted on the sleeve, and a spring interposed between the flange and said abutment.

3. A music roll provided at its end With a stud, a sleeve mounted on said stud and provided With a cap, a flange mounted on said stud and provided in its outer side with a recess which receives said cap, and a spring arranged in said recess and hearing at its endsagainst the cap and the bottom of the recess.

4. A music roll provided at its end with a stud, a sleeve mounted on said stud and having a projecting abutment at its outer end, a flange mounted on said stud and having the outer portion of its bore enlarged, forming a shoulder therein, and a spring surrounding said sleeve Within the enlargement of the flange-bore and bearing at its ends against said shoulder and said abutment.

5. A music roll provided at its end With a stud, asleeve mounted on said stud and having a projecting abutment-flange, a rollfiange mounted on said stud and having the outer portion of its bore enlarged, forming XIVILLIAM F. BAYER.
